P0101 keeps coming on and off on my 2001 zr2 blazer. After numerous searches on the forum im stumped at what to do. I have cleaned the MAF sensor with maf cleaner and I have also changed the fuel filter. Changing the fuel filter helped the sluggish performance when I would get on the throttle (3/4 or more). Besides that little issue there is no change in the way the truck runs. A few weeks back, and before I had changed the fuel filter I was on a long trip, 3+ hrs on the highway and the p0101 code popped along with p0151 and p0131. Truck ran like crap and felt like it was dropping a cylinder. It happened about 50 miles away from home and it was late so i parked it and figured i would mess with it in the morning. In the morning i just cleared all the codes and just figured I would see the order in which they come back up. Only thing that came back was the p0101. Now the code seems to come and go as it pleases. I dont have a high end reader, all I can do is read and clear codes with it. Any help as to what to do next would be appreciated. I am running a cold air intake but ive had it all summer with no issues. also, not sure if it matters but I just had to put a new tranny in it and the code started appearing shortly after that. I dont feel like they are related though.

 

No one?

 

Have you checked the wiring to the MAF? Made sure you have good power and ground? The center wire is ground, the one to the right of it is power (12v) red wire.
